AT&T Internet Speed Test

Mobile users should open their preferred speed test app to test their speed.
Check upload and download times with the AT&T Internet speed test. Measure how fast files download or upload from the Internet to your computer or mobile phone and define bandwidth performance.

What are we measuring?

The speed test takes less than a minute and performs two key measurements:

Download speed (the speed of data sent from the Internet to your computer)

Upload speed (the speed of data sent from your computer to the Internet)

We also report latency and jitter, factors that could influence your speed.
